9. RECOGNITION OF ABNORMAL OPERATION

9.4 No Hot Water

1) Check if the power is switched on. Check that the isolating switch, to which your Solarstream

is connected, is switched on. Check that the switch marked “Water Heater” on your power

switchboard is turned on. Check that all circuit breakers have been reset.

If you are connected to Off Peak or a Smart Meter, check that you have power supplied when

checking the operation of your Solarstream.

2) Check that the thermal overload (on the digital controller) has not tripped. Turn the power off

then back on to perform a re-set action.

3) Check whether the Pressure & Temperature Relief valve is discharging too much water

(refer to Section 4.4).

4) Check that you have the correctly sized water heater for your requirements. Sizing details are

available from your plumber or Siddons. The rule of thumb is 30-50 litres per person per day,

more in winter, less in summer.

5) Check your household water usage. Is one outlet (such as the bath) using more hot water than

you think? Review your family's hot water usage and if necessary check the shower flow rates

with a bucket and measure this. Consider installing low volume shower heads and other

measures to reduce hot water usage.

9.3 Steady Flow

If you notice a steady flow of water from the PTR valve, then this may be caused by excessive

water supply pressure. Note, a 500kPa Pressure Limiting valve must be fitted. It may also be

caused by a faulty Pressure & Temperature Relief (PTR) valve, or a faulty Thermostat / Digital

Controller. Turn off the power and contact a qualified technician or Siddons for help (refer S4.7).

9.2 Continuous Trickle

If you notice a continuous trickle of water from the PTR valve, this is likely due to a build up of grit

or scale. Lift the lever to release water for a few seconds from the PTR valve. This may dislodge

small particles of foreign matter to rectify the fault. It is normal for the PTR valve to release a

small quantity of water during the heating cycle. The amount of discharge will depend on hot

water usage. As a guide, if it discharges more than 20 litres of water in 24 hours then there may

be a problem (refer Section 4.4 and 7.3).

AIR TO WATER ALL IN ONE HEAT PUMP

9.1 Start up Delay

NOTE: The heat pump has a 3-minute time delay on re-start. If the power to the heat pump is cut

during its heating cycle, then a time delay period will commence upon re-start. The compressor

and fan will not operate until the completion of this delay period.
